Cloudy Stalevoy
Cloudy Stalevoy (#270B11) is a deep red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (347°, 56%, 10%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
An adjectival form of cloud — used as a color modifier since the medieval period for hues that read as overcast or slightly hazed. Cloudy gray, cloudy white: low saturation combined with optical mattness. Sits at the neutral-bucket alongside misty and fog.
Russian стальной, steel-gray — adopted into Russian color terminology for the deep-cool-gray of Magnitogorsk and Nizhny Tagil Soviet-era steelworks ingots. Stalevoy color refers to a Magnitogorsk-Steelworks-cast steel ingot face in raking light: a dark cool-gray with the metallic finish of multi-element Magnitogorsk-formula steel-cast on hand-poured Soviet-foundry ingot mold.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
